Landscape, at most 500px tall, touch input (a sideways phone is ~840px
wide, the Tablet size class, so the trigger is the screen shape), in this
room's joined call, chat closed: the call takes the whole screen. No room
header, sidebar or call-status bar; safe-area insets respected.
- Taps inside the call frame never reach the app, so while the controls
are hidden a transparent layer covers the call: the first tap shows the
call bar plus Chat / Exit full screen, which hide again after 4 s
without a touch; with them up the call underneath stays usable.
- In an Android browser tab the first tap also enters the browser's own
full screen (hides the address bar); left again on rotate back, hang
up or exit. No effect on iPhone or the installed app.
- Exit full screen lasts until the phone is upright again.
- The frame is transparent (room wallpaper), so in full screen it gets an
opaque base colour under the wallpaper.
